To all whom 'it may concern-.- l

Be it known that l, EDGAR P. WEBSTER, a citizen of the UnitedStates,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inDevices for Operating Transoms and Shutters; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to certain improvements in devices for operatingtransoms and shutters, and consists of certain combinations andarrangements of parts, such as will be hereinafter fully described andthen particularly pointed out the claims which conclude thisapplication.

r The object of my invention is to provide a device of this descriptionwhich shallbe readily operated and not likely to get out of order.

In the accompanying drawing which forms a part of this applicationFigure 1 is an elevation of the outside of a` shutter as it appears whenequipped With my improvement- Fig. 2 a section at the line a, a, of Fig.1, the position of the shutter being shown as closed--Fig 3 a viewsimilar to Fig. 2, butshowing the position of the parts when the shutteris open-Fig. 4 a detail elevation of my improvement with the shutteroperating lever removed-Fig. 5 a view similar to Fig.` 4 but with one ofthe cheek plates removed and showing the pinion in section-Fig. 6 asection at the line b, b, of Fig. 2-Fig.,7 a front elevation showing myimprovement` as it appears when applied in position to operate atransom, the latter being shown in closed position-Fig. 8 a sideelevation of the construction and arrangement shown at Fig. 7, thetransom bein shown openFig. 9 a detail elevation part y in section ofthis transom operating device, taken at the line c, c, of Fig. 10-Fig.10 a section taken at the line d, d, of Fig. Q-Fig. 11 a view similar toFig. 9 but showing a modification of my improvement, this view beingtaken at the line c, e, of Fig. 12-Fig. 12 a section taken at the linef, f, of Fig. 11-Fig. 13 a detail elevation showing the manner in whichthe operating lever is preferably secured, and Fig. 14 a section at theline g, g, of Fig. 13.

Similar numbers of reference denote like parts in the several iiguresofthe drawing.

My improvement is adapted for use for the purposes of operating either atransom or a shutter and in order to give a clear understanding of myinvention I have illustrated the same in connection with both a shutterand a transom, but the mechanical operation of the parts is the same inboth instances, and l will therefore confine my description as todetails mainly to the operation of my device in connection with ashutter, it being of course understood that I do not thereby limit thefield of operation of my improvement. f

The following description in detail refer to Figs. 1 to 6 inclusive,which description, together with the numerals of reference employed willapply without repetition to Figs. 7 to 14 inclusive.

1 is an ordinary window casing which is mortised at 2 on the outside forthe purposes presently to be explained.

My improved device comprises a face plate 3 which has an elongated slot4, on one side of which is a cheek plate 5 preferably cast integral withthe front of the plate 3 while on the other side of said slot andpreferably cast integral with the front of the plate 3 are lugs 6 towhich are secured by means of screws 7 a cheek plate 8 which latter is oposite to the plate 5 and is made detachab e merely for the purposes ofconvenient assembly of the arts. Journaled within these cheek plates 1sa short shaft 9,

and carried by this shaft between the cheek plates and preferablyintegral with said shaft is a pinion 10, the lower extremity of saidshaft being squared as shown at 11 for the purposes presently to beexplained.

12 is a segment gear lever which is pivoted at 13 to a lug 14 whichextends from therear of the plate 3, the teeth of this gear being inmesh with the pinion 10.

15 is a shaft j ournaled within brackets 16 cast integral with the rearface of the plate 3, this shaft being screw threaded as seen at 17.

18 is a nut engaging said shaft and having a small post 19 projectingtherefrom with Which post the rear end of the lever 12 is looselyconnected, by means of an elongated opening 20 in said lever.

21 is a sprocketwheel which is secured to one end of the shaft 15, whichlatter is incapable of lengthwise movement, so that it will be readilyunderstood that when said shaft is revolved the nut 18 will be caused totravel thereby swinging the lever 12 on its pivotal point and effectingthe revolution of the pinion 10.

of the shutter.

My improved device is placed within the inortise 2 and secured by meansof screws 22, and a suitable chain 23 is passed around the sprocket 21,the ends of this chain being led out through metal thimbles 24 and overfriction rollers 25 and thence allowed to depend within convenientaccess.

26 is a long lever one end of which is secured around the square end 11of the shaft 9 outside the window casing, and held in this position bymeans of a nut 27, while the other end of said lever is equipped with anangularly disposed hook 28 which passes through an elongated slot 29 ina plate 30 that is secured to the outer portion of the shutter, theconnection between this hook and slot being such that the former mayreadily travel throughout the latter.

The operation of my improvement is as follows r-The two ends of thechain 23 are properly marked or otherwise identified so that theoperator will readily know which chain must be pulled in order to openor close the shutter, as the occasion may demandl The blind being inclosed condition a pull upon the proper chain will cause the sprocket torevolve thereby effecting the turning of the pinion whereby the longlever 26 will swing outwardly to open the shutter, this pullingk of thechain being continued until the shutter has been swung completely back,as shown at Fig. 3. Pulling on the other chain will of course effectrthe closing pulled to leave the shutter open to any desired degree, andthe latter will stay in this position because any force brought to bearupon the shutter itself to operate the same will be resistedl by the endthrust of the nut 18 against the/screw thread 17.

In applying my improvement for the purposes of operating a transom, theface plate 3 is secured directly to the transom casing 31 without anymortising, and all the operative parts are on one side only of saidplate, this being necessary owing to the fact that the transom isoperated in a vertical plane while the operation of the shutter is in ahorizontal plane.

Referring to Figs. 7 to 14 inclusive, which relate to the application ofmy improvement in connection with a transom, I will point out thedifferences as to minor details.

Extending. from the face plate 3 and integral therewith is the cheekplate 32 and skeleton frame 33, while a cheek plate 34 and skeletonframe 35 likewise extend from said plate 3 but are detachable therefromfor the purpose of convenient assembly of parts, this detachable cheekplate being secured at one end by a screw 36 to a lug 37 extending fromthe plate 3, while the end of the skeleton frame 35 is secured at itsbase by means of a screw 38 directly to the base of the frame 33.

The proper chain may be The short shaft 9 carrying the pinion 10 isjournaled between the plates 32, 34, and the segment gear lever 12meshes with this pinion and is pivoted at 39 between the plates 32, 34,and is loosely engaged at its rear end with the post 19 projecting fromthe nut 18 which latter engages the screw threads 17 on the shaft 15, onwhich latter the sprocket wheel 21 is secured, all in the manner and forthe purpose hereinbefore explained with reference to the adaptation ofmy improvement for the purpose of operating the shutter.

The shaft 15 is journaled within the plate 3 and the top of the frames33, 35, and the revolution of the sprocket wheel will cause the nut 18to travel, thereby swinging the segment gear lever and operating thepinion, all in the manner as heretofore explained.

The location of my device, when the same.

is applied for the operation of a transom, renders it advisable toprovide for an adjustment of the-normal yposition of the long lever 26,since the casing of the transom sometimes extends considerably beyondthe vertical plane of the closed transom, and said lever must reachinwardly far enough so as to completely close the transom. I therefore,in thisinstance, arrange the lever on the 'rounded portion of the shortshaft 9 so that said lever will swing freely around said shaft, and' onthe squared portion 1l of the shaft I secure a plate 40 by means of anut 41, which plate near its outer edge is provided with an arcuate slot24 through which a threaded bolt 43 carried by the lever extends freely,a nut 44 driven against said plate 4() serving to lock the lever andplate together in any desired adjustment.

The weight of a transom is frequently very great, and in order toprevent'a shock when the transom is dropped, I provide a coil spring 45around the short shaft, one end of which spring is secured within theshaft itself while the other end is connected with one of the cheekplates, so that when the transom is lowered the spring will wind andtherefore allow the transom to be dropped easily, while the unwinding ofthe spring, as the transom is raised, will materially assist in theoperation of closing the transom.

Instead of imparting movements to the segment gear lever from the screwthread 17 through the medium of the nut 18, said nut may be dispensedwith, and the rear end of said lever formed into a worm wheel segment 46which latter will engage directly with the threads 17, as shown in themodification at Figs. 11 and 12, and I therefore do not wish to belimited in this respect.

The object of the sprocket wheel and the chain is of course to provide aconvenient way of revolving the threaded shaft 15 in reverse directions,so as to open and close the transom or shutter, but any suitable and orgdinary means may be employed for this purpose, as for instance, a chainsecured to the shaft and then wound around the same so that the pullingof one end of the chain would revolve the shaft in one direction andwind up the other end of the chain, While the reverse would be true whenthe latter end was pulled, and I therefore do not wish to be limited inthis respect.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is z` 1. In a device of the characterdescribed, the combination of a face plate provided with cheek plates, ashort shaft carrying a pinion and journaled within said cheek plates, apivoted segment gear lever meshing with said pinion, a threaded shaftjournaled between supports carried by said plate, a sprocket wheelcarried by said shaft, a chain around said sprocket and having its endsdepending within convenient access, connections between the rear end ofsaid segment gear lever and said threaded shaft, whereby the latter willcommunicate swinging movements to said lever, and a long operating levercarried by said short shaft and suitably connected with the shutter ortransom to be operated.

2. In a device of the character described, the combination of a baseplate carrying cheek pieces, the short shaft carrying a pinion andjournaledwithin said cheek pieces, the segment gear lever meshing withsaid pinion and pivoted to a part rigid with the face plate, thethreaded shaft journaled within supports carried by said plate, the nutaround said shaft and loosely connected with the rear end of saidsegment gear lever, the sprocket carried by said threaded shaft, thechain around said sprocket and having its ends depending withinconvenient access, and the long operating lever carried by said shortshaft.

3. In a device of the character described,

4. The combination of a rotary shaft carrying a pinion, means forconnecting said shaft with a transom or shutter whereby the latter willbe operated by the rotary movements of the shaft, a'pivoted levercarrying a segment gear in mesh with said pinion, a threaded shaftstationary as to lengthwise movement, a nut on said threaded shaft andloosely connected with said lever whereby the travel of the nut willcause said lever to swing around its pivotal point, and means convenientof access and connected with said threaded shaft for revolving the same.

5. In a device of the character described, the combination of a rotaryshaft carrying a pinion, means for connecting said shaft with a transomor shutter whereby the latter will be operated by the rotary movementsof the shaft, a reciprocatory lever carrying a gear in mesh with saidpinion, a rotary. threaded shaft, connections between said lever andthreaded Shaft whereby the latter will communicate reciprocatorymovements to said lever, and means for revolving said threaded shaft inreverse directions.

In testimony whereof I afiix my signature in presence of two witnesses.
